Programmatically Created Template Columns Have Contents Disappear On Detail Table Expand?

Hi,

I'm trying to build a RadGrid and I wanted to use Template columns programmatically, so I followed the tutorial here and everything worked brilliantly. I even got as far as beginning to create a template for the editing and adding of new records. The problem however has occurred that I've added a series of detail tables to my grid and now when I click to expand in to one of the detail tables the Bound columns that I've added to the Master Table still maintain their values but the Template columns completely lose their values.

I don't know if I'm missing something or I'm doing something in an incorrect way but the template columns display so perfectly and the fact that they disappear whenever you expand the grid is really disheartening.

Here's the code:

Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

RenderOrderGrid()

End Sub

Private Sub RenderOrderGrid()

Dim myDataSet As DataSet

Dim rgdOrders As RadGrid

Batch EditMode - Change item template css class on cell changed value

Hi!

I am using a radgrid in batch EditMode with EditType Cell.

Inside the grid i have several GridTemplateColumns with a raddropdown control each, which should change style according to the value selected on each.

I am trying to find a way on BatchEditClosed or BatchEditCellValueChanged events to re-attach the css class that i use in ItemTemplate for dislpaying the selected value.

Here is my grid:

<telerik:RadGrid

RenderMode="Lightweight"

runat="server"

ID="RadGridLesions"

AllowPaging="True"

AllowSorting="True"

AutoGenerateColumns="False"

Skin="BlackMetroTouch"

CssClass="dark-grey"

OnNeedDataSource="RadGridLesions_NeedDataSource"

OnPreRender="RadGridLesions_PreRender"

OnItemDataBound="RadGridLesions_ItemDataBound"

ShowStatusBar="True"

AllowAutomaticInserts="False"

AllowAutomaticDeletes="True"

AllowAutomaticUpdates="True"

ItemCommand="RadGridLesions_ItemCommand"

UpdateCommand="RadGridLesions_UpdateCommand"

DeleteCommand="RadGridLesions_DeleteCommand"

OnBatchEditCommand="RadGridLesions_BatchEditCommand"

>

<MasterTableView

CommandItemDisplay="Top"

EditMode="Batch"

DataKeyNames="Id, Segment, Level, Side"

Name="GradesTable"

>

<PagerStyle />

<BatchEditingSettings

SaveAllHierarchyLevels="false"

HighlightDeletedRows="false"

EditType="Cell"

OpenEditingEvent="Click" />

<Columns>

<telerik:GridTemplateColumn

HeaderText="T2"

HeaderStyle-Width="70px"

ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center"

UniqueName="T2Grade"

DataField="T2Grade">

<ItemTemplate>

<div id="T2Grade-container" class='<%# "grade a" & Eval("T2Grade") %>'>

<%# Eval("T2Grade") %>

</div>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadDropDownList

RenderMode="Lightweight"

runat="server"

ID="T2GradeDropDownList"

AutoPostBack="false"

Skin="BlackMetroTouch"

SelectedValue='<%# Eval("T2Grade") %>'>

<Items>

<telerik:DropDownListItem Text="1" Value="1" CssClass="one" />

<telerik:DropDownListItem Text="2" Value="2" CssClass="two" />

<telerik:DropDownListItem Text="3" Value="3" CssClass="three" />

<telerik:DropDownListItem Text="4" Value="4" CssClass="four" />

<telerik:DropDownListItem Text="5" Value="5" CssClass="five" />

</Items>

</telerik:RadDropDownList>

</EditItemTemplate>

</telerik:GridTemplateColumn>

The issue i have now is that if i select a different value in the drop-down the styling of the "old" one remains and changes only when i press the save button.

I would like to re-evaluate the expression attaching the css class to the div (class='<%# "grade a" & Eval("T2Grade") %>') on client side, when the value is changed in the drop down.

I assume i can do that like:

function BatchEditCellValueChanged(sender, args) {

//alert(BatchEditCellValueChanged);

var grid = sender;

var masterTableView = sender.get_masterTableView();

var batchEditingManager = sender.get_batchEditingManager();

var row = args.get_row();

var cell = args.get_cell();

var tableView = args.get_tableView();

var column = args.get_column();

var columnUniqueName = args.get_columnUniqueName();

//new value

var editorValue = args.get_editorValue();

//old value

var cellValue = args.get_cellValue();

if (args.get_columnUniqueName() === "T2Grade") {

//try and change css class of edited cell -

//something like: cell.findElement("T2Grade-container").className = "<%re-evaluate expression%>";

}

Any ideas on how i can achieve that? Up to the moment i have not found a way to grad the div element inside the itemTemplate and change its css class.

Custom Aggregate with Details Tables

I spent some time looking around for info on this and didn't find a good answer as to how to do this without having to use the detailstable databinding and databound events. In all the examples I found they all used the radgrid.MasterTableView.Items collection specifically. My solution turned out to be simpler by using e.Column.Owner.Items from the GridCustomAggregateEventArgs. By checking the e.Owner.Name that is set in the designer properties I can then tell which table that I'm trying to preform the custom Aggregate for and return different results.

In an effort to save others some time here, I'm posting some example code for this.

Protected Sub rg_CustomAggregate(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCustomAggregateEventArgs) Handles rg.CustomAggregate

Dim i, j, k, l, m, n As Integer

For Each di As GridDataItem In e.Column.Owner.Items

If e.Column.Owner.Name = "MainTableName" Then

'preform you custom aggregation calculations

i += CType(di.GetDataKeyValue("maintablecolumn1"), Integer)

j += CType(di.GetDataKeyValue("maintablecolumn2"), Integer)

k += CType(di.GetDataKeyValue("maintablecolumn3"), Integer)

e.Result = Decimal.Round(Convert.ToDecimal((i + j) / k * 100), 2)

End If

If e.Column.Owner.Name = "DetailTableName" Then

l += CType(di.GetDataKeyValue("detailtablecolumn1"), Integer)

m += CType(di.GetDataKeyValue("detailtablecolumn2"), Integer)

n += CType(di.GetDataKeyValue("detailtablecolumn3"), Integer)

e.Result = Decimal.Round(Convert.ToDecimal((i + j) / k * 100), 2)

End If

Next

End Sub

[Solved] Calendar as a ComboBox Template issues

Im creating an user control. In my control I need to create programmatically some Combo Boxes. In some cases, I need a Calendar as a Template in my comboBox but im facing two situations.

1. I cannot deselect dates in my calendar. Once I make a selection, calendar has always at least one selected date and if I click the selected day, this day remains selected.

As you can see in the 1.gif file attached, I can select dates normally but I try to deselect by clicking on 15th several times and I'm not able to. I can change the date selection (I moved to 12th) but is not possible to unselect.

2. When I clic Calendar header to choose years and mothes, the popup appears behind the combobox. See 2.gif

Javascript fucntions

function OnClientDropDownClosing(sender, args) {

if (args.get_domEvent().target == sender.get_imageDomElement()) {

args.set_cancel(false);

}

else {

args.set_cancel(true);

}

function OnClientDropDownClosed(sender, args) {

var SenderId = sender.get_id().replace("FiltrosNativos_","");

var CalId = SenderId.replace("RadComboBox", "RadCalendar");

var Cal = sender.get_items().getItem(0).findControl(CalId);

var dates = Cal.get_selectedDates();

if (dates.length == 0) { sender.set_emptyMessage("Elija Fechas"); }

else {

var dt1 = dates[0];

var dt2 = dates[dates.length - 1];

var rango = dt1[2] + '/' + dt1[1] + '/' + dt1[0] + ' -- ' + dt2[2] + '/' + dt2[1] + '/' + dt2[0];

sender.set_emptyMessage(rango);

exporting hyperlink to excel

Hello,

I have read the other threads, and I am not having much success. I can export a URL as text, but I haven't been able to get it to show up as a clickable link in an xlsx file. Can someone please help me? Below are the examples preceded by a note about its behavior:

Chart of Time, include missing dates

Hi

I am using the asp.net charting control. I am plotting data over time, sometimes over days, weeks, months and years. I would like th X axis (which shows time) on the graph to be sequential even if the data is not. eg, if a week/month/year is missing it will plot a the item on the X axis but not have a value (hope that makes sense). So effectively the chart looks like a timeline of data, the gaps shows missing data

Is this possible with the chart control?

Many thanks in advance
